We have a school-use diagnosis from the IEP team which included all of the above.
I will, say, however, that the call was left to the psychologist. The others didn't feel it was within their expertise to title it. What they did, instead, was assess exactly where my son was at within their discipline. Pragmatic speech, motor skills, etc.
The IQ test, however, was important to the psychologist's call. Many AS have highly variable IQ scores, in that some components of IQ will be very high, and others very low. NT's, I guess, don't usually exhibit that disparity.
